Direct injection Diesel-style engines emit solid-phase carbonaceous particulate matter (i.e. soot) at levels that negatively impact both climate change and personal health. Although advances in injection technology have increased atomization and mixing of the injected fuel jet, which reduces local equivalence ratios and decreases soot formation, aftertreatment is still required. This in turn ha...

Energy intensive industries, such as the bulk chemical industry, are facing major challenges and adopting strategies to face these challenges. This paper investigates options for clusters of chemical process plants to decrease their energy and emission footprints. There is a wide range of technologies and process integration opportunities available for achieving these objectives, including (i) ...

The analyzed electrohydraulic servo valve is jet pipe type, is one of the mechatronics component used for precision flow control application. The jet pipe servo valves have one movable nozzle and two collector ports, from where fluid is ducted to the main valve spool. The servovalve analyzed here is basically used in fuel control application in Variable Geometry Actuation System (VGAS) of a gas...

A procedure for estimating fuel burned based on actual flight track data, and drag and fuel-flow models is described. The procedure consists of estimating aircraft and wind states, lift, drag and thrust. Fuel-flow for jet aircraft is determined in terms of thrust, true airspeed and altitude as prescribed by the Base of Aircraft Data fuel-flow model. This paper provides a theoretical foundation ...

a newly developed heavy duty diesel engine in dual fuel mode of operation has been studied in detail. the main fuel would be natural gas and diesel oil as pilot injection. the importance and effects of mixture preparation and formation through ports, valves and in cylinder flow field with different swirl ratio and tumble on diesel combustion phenomena is an accepted feature which has been studi...
